☆System principle
The World Expo Park Vehicle Safety Supervision System is based on automatic vehicle identification and certification services. It focuses on solving the problem of “automated vehicle identification and certification†and provides a technology platform for the “Regional Road Traffic Environmentâ€-related vehicle safety supervision.
By installing different types of electronic documents with high anti-counterfeiting capabilities working on passive ultra-high frequency bands, the unique correspondence between electronic certificates and vehicles is implemented to realize the “electronic identity mirroring†of the vehicles entering the park, combined with the image video recognition mechanism. The static information identifying the object (vehicle) is combined with dynamic information (time and road space information) organically.
When the vehicle passes through the campus entrance and exit to inspect the base station, the system automatically collects the vehicle's electronic certificate information and image information. The background database will determine the legality of accepting the vehicle information. When the vehicle's identity information, access information and the base station's image and radio frequency information are completely the same. , be released, and automatically record vehicle-related traffic information into the back-end database.
By creating an “identity standard source†that fully supports modern information technology, the system fully develops and serves information resources in this field, and builds a safety supervision system involving vehicles based on modern information technology to meet the needs of multiple types of public security police. Car policing operations needs, including the following technical protection and control services: automatic collection and analysis of full-sample “car and driving†information, vehicle access control in key prevention areas, automatic attack of counterfeit vehicles, blacklist vehicle investigation Dispatch control, vehicle operation status check and track backtracking, etc.
The system has the ability to adapt quickly to the development of business processes. It can efficiently and reliably complete the supervision of running vehicles without affecting the original state of transportation. It has the technical conditions for a public service platform involving vehicle-related information and supports various types of social-related industries. And the user's service business. ☆System composition
The World Expo Park Vehicle Safety Supervision System consists of a card management system, a base station group, an information center, and an information service platform. The base station group system and the card management system together form the hardware foundation of the system, and the information center and information service platform (collectively referred to as information services). System) constitutes the service core of the system, the former provides data support for the latter.
———Card Management System
The "two-phase" type (ie, "Physical Life" phase and "System Life" phase) of the vehicle's electronic credentials is followed by the full life cycle follow-up supervision. The card management system is responsible for implementing two-stage life-cycle tracking management, validity authentication and information maintenance, and acquiring and establishing an automotive user information archive system for the system during the system life cycle management process of the electronic certificate. The other related subsystems in China provide customer information services.
———Base station group
The base station group is a receiving/transmitting terminal for entering car information. On the one hand, through the base station system to collect the vehicle's electronic documents and image information, to achieve the vehicle admission inspection and release, and related records sent to the information center; the other hand, according to the information center to provide the black list, the implementation of vehicle deployment.
---information Center
The main function of the information center is to collect and analyze and distribute various vehicle information. The information center can be divided into a central information center and a partition information center according to a hierarchical structure.
The Central Information Center, as a regional data exchange and coordination center, uses the public security network to implement inter-regional car blacklist information and illegal online transmission of illegal information to achieve the sharing of illegal information in the park; partition information center is responsible for Communication with the base station and provide information services and management.
———Information Service Platform
The service platform is a manifestation of the application of the vehicle safety supervision system in the Expo Park, including the application platforms of various functional departments at various levels, such as traffic management platforms, emergency rescue platforms, and public security and personal service platforms such as travel information service platforms, vehicle safety platforms, etc. . ☆ Typical process design
The Expo Park Vehicle Safety Supervision System implements the entry inspection for the vehicles entering the park. Its core lies in the legal determination of the two mechanisms of radio frequency identification and video recognition. The video capture and forensics function module performs video capture and license plate recognition on passing vehicles; the radio frequency identification system The vehicle electronic certificate information is collected. After the vehicle enters the system read-write area, it automatically reads the vehicle information and compares the read information with the background information.
After the vehicle enters the inspection area, the video module automatically recognizes the vehicle number plate. The radio frequency identification system reads the electronic certificate information, compares the consistency of the captured picture information and the electronic certificate information, and compares the results and releases the information to the information center.
